Essay on Wind Turbine Top 7 Essays
2022 4 10 Since a tower produces turbulence behind it the turbine is usually pointed upwind of the tower Turbine blades are made stiff to prevent the blades from being pushed into the tower by high winds Additionally the blades are placed a considerable distance in front of the tower and are sometimes tilted forward into the wind a small amount.
